Question

on 500g mass a force of 3N acts at an angle of 60 find work done in 5 second​

Answer 1

Answer:

650 seconds

Explanation:

Answer 2

Explanation:

mass of the ogject=5Kg.

force applied=3N.

time taken=5 sec.

angle of elevation=60 degree.

force=3N.

THEREFORE

Mass(acceleration)=3N.

5Kg(acceleration)=3N.

THEREFORE ,

ACCELERATION=3/5

=0.6m/sec squared.

acceleration=0.6m/sec squared.

velocity/time taken=0.6

velocity=0.6(5)

=3m/sec.

velocity=3m/sec.

displacement/time=3m/sec.

therefore,

displacement=3(3).

displacement=9m.

therefore WORK DONE

=FORCE(DISPLACEMENT)(Cos 60).

=3(9)(1/2).

=27/2.

=13.5J.

THEREFORE WORK DONE =13.5J.
